.WEB-ROLL RELOADING nmcnaNrsu.

)roblems arise in accommodatiiw these ma chines in the pressroom space which can be afforded them, and where, as is frequently the case, this space 15 cramped the prlnting units of the machines have to be placed very close together. These machines use a large number of rolls and a spare roll supply must always be ready for use to take the place of therunning rolls as these are exhausted. \Vhere the pressrooin space is small and the couples have to be placed close together, difficulty is experienced in positioning the spare rolls for use while the press is using the running rolls. Furthermore, these rolls are very heavy and are difficult to handle and place in position.

A special object of the present invention is to provide an improved mounting or support for the rolls so that spare rolls may be placed in position without interfering with the running rolls where the space for the running and spare rolls is very small or confined. e

A further object of the invention is to provide an improved mechanism for positioning the rolls in their bearings, particularly in narrow and confined areas. I

V ith these and other objects not specifically referred to, the invention consists in certain novel parts, arrangements and combinations which will be described in connection with the accompanying drawings and the novel features pointed out in the claims hereunto annexed.

In these drawings,

Figure 1. is a side elevation of a multicouple printing machine which illustrates the invention;

Figure 2 is a detail plan view, partly in section, of one of the-roll supports .in operative or running position, and

Figure is a similar view showing in dotted lines the support moved to permit the loading of a roll.

' Referring now to these drawings, the invention has been illustrated as employed in a multi-couple rotary printing machine in which the couples are arranged closely together, as is necessary in many instances on Application filed February 5, 1925. Serial No. 8,887.

account of lack of space in the pressroom, and two adjacent printing couples of such a machine have been shown. It will be understood, however, that the invention may be used in other relations than inthe particular machine illustrated.

In the press shown, there is-provided a printing unit A, including a form cylinder 1, an inlpression cylinder 2 and the impression cylinder 3 of a perfecting couple. Closely adjacent. this couple is a second printing couple B having a form cylinder 4, an impression cylinder 5 of a perfecting couple and the impression cylinder 6 of a printing couple. The couples are inked in the usual manner from distributing cylinders 7 with their trains of ink rolls 8, these parts being supported in suitable side-frames 9 rising from a base in the form of a frame 10. These parts of the press are driven in any usual desired manner, as from a power shaft 11 and driving shafts 12, 13.

The paper rolls in these presses are supported in brackets which extend outwardly from suitable supporting frames, the rolls being lifted from trucks and positioned in these brackets. space. the printing couplesand the rolls that feed them have to be placed closely adjacent, difiiculty has been found in enabling a spare .roll to be passed by a running roll to get' it into position, the brackets interfering with position that spaceis provided for a roll to be moved into position past a running roll without interfering with the latter. While this may be accomplished in various ways, in the particular construction illustrated, the roll supply is carried beneath the presses, this construction being adopted so that the rolls will have to be lifted at minimum height to get them in position. As shown, therefore, the base frame 10, before referred to, is supported on upright frames 14, 1 5, which in turn serve as supports for the roll holding brackets 16, 17 these brackets being arranged in pairs on opposite sides of the machine, those atthe front side of the machine only being illustrated. One of these sets of brackets, as the? bracket 16, supports a ,roll, shown as the running roll R, which feeds couple A, and a similar set of brackets here, because of crampedi on the other side support a s are roll R.'

The bracket 17 supports a roll or supplying couple B, this roll being shown as exhausted, and a spare roll S being shown asaboutto be raised into position, the couple B being fed' at this time from a roll S', shown in dotted lines in Fig. 1.

It" will be observed that if the brackets 16, 17 were, as is usual, fixed brackets the a roll being moved into position. While various expedients for preventing this may v be provided, in the articular construction illustrated, this ise ected by pivoting the brackets so that the brackets may be swung sidewise in their supports at an angle to their normal posit-ion, with the result that an additional space, the width of a bracket, is provided which is sufficient to permit the ready handling of the rolls.

' The construction of the brackets is identical and the description of one will suffice for all. As shown and referring to bracket 16, this bracket is supported in a plate 18 suitably secured, as by bolts 19, to the upright frame 14, before referred to. This plate and the bracket are provided with knuckles 20, 21 which receive hinge pins 22, on which the bracket can be swung from the position shown in full lines in Fig. 3 to the position shown in dotted lines, that is, at right angles thereto, so that sufficient space is provided for permitting the passage of a spare roll past the running roll and past the supporting brackets. These brackets carry the usual brake mechanism for breaking the rolls, indicated at 23, and a socket, shown at 24:, in which the roll runs.

The front end of the bracket is also provided with an arm 25 pivoted at 26 there-' to, this arm being lifted to raise the roll from a truck 27 so that the roll may be moved into running position in the bearings 24;. In accordance with the invention, means are provided whereby this arm 25 may be lifted without the necessity of an operator getting between the rolls to lift the arm, thus further economizing space, the means for lifting this arm being located above or to one side of the bracket. \Vhile these means may be of various characters, in the particular construction illustrated, there is provided a sheave 28 secured in a convenient position to the frameIO, before referred to, this construction being duplicated at the back of the machine. This sheave supports lifting cables 29 which are provided with hooked ends 30 which hook over pins 31 in the ends of the arms 25. These cables -at their other ends are secured to ashaft 32, on one endofwhich is a gear. 33 yl ;ieh

meshes with a pinion 34 on a stud havlng a squared end 35 which will receive a wrench handle by which the pinion may be rotated, this shaft 32 and the pinion 35 being mountedi'n a bracket 36 suitably secured to one of the uprights, as the upright 15, before referred to. It will be understood that as many of these lifting cables as are necessary will be provided foi' 'manipulatin the 'rolls of any given press.

- hile the invention has been-shown'and described in its preferred form, it will be understood that certain changes may be made in the specific structure shown and described without departing from the invention'as defined in the claims hereunto appended. l

What I claim is:

1. In a printing machine, the combination of a plurality of rinting couples, of spaced framing supporting the couples, web roll supports secured on adjacent sides of the framing and extending outwardly there .from facing each other with a clear space between them, and means foi' swinging the supports at an angle to the framing to form a clear path for the roll. so that a roll may be entirely moved past the support for positioning therein without interfering Y with a roll running in the opposite support.

2. In a printing machine, the combination of a plurality of printing couples, spaced frames below the couples andsupporting.

them, pivoted brackets secured to adjacent sides of opposite frames and extending outwardly therefrom facing each other with a clear space between them, said brackets having a swinging movement angularly to the frames to form a clear path for the roll so that a roll may be entirely moved past the bracket for positioning therein without interfering with .a roll running in the opposite bracket.

3. In a printing machine, the combination of a plurality of printing couples, of spaced I framing below the couples and supporting them, web roll supports mounted on adjacent sides of the framing and extending outwardly therefrom facing each other with a clear space between them, means for swinging the supports at an angle to the framing to form a clear path for the roll, so that a roll may be entirely moved past the .support for positioning therein without interfering with a roll running in the opposite support, a roll hoisting mechanism, and meanslocated'above and between the roll supports for hoisting a roll onto the support.

In testimony whereof, I have hereunto set my hand.
